I'm trying to increment a value in NSMutableArray when an action is done and it is giving me the following error

Cannot assign to immutable expression of type 'int'.

self.itemsArray[tag][itemType]!![itemType]!!["likeCount"] as! Int = self.itemsArray[tag][itemType]!![itemType]!!["likeCount"] as! Int +1

this was my line of code . And I'm pretty sure thats an Int. I'm trying increment the value present in likeCount.

Please help me.

Thanks.

    Note: it looks like you should not use dictionaries for your use case. I would rather use arrays of custom structs, for example. Dictionaries with nested values are not the most convenient data structures in Swift. At all. :) Commented Jul 18, 2016 at 14:40
